The present invention is directed to improvements in strainers.

The primary object of the invention is to provide a strainer designed more particu- 5 larly for use in connection with pasteurizing apparatus,-but of course is not limited to such use. v I 1 Another object of the invention is to provide a device of this character so constructed that the screen material 7 after a period of use in order that an unused portion of the material will be positioned for straining the liquid- I Another object of the invention is to pro- 1 vide a deviceofthis character wherein the straining material is mounted upon a pair of rolls, means being provided whereby the material can berolled from one roll to the other in order that clean or unused parts of thematerial can bepositioned for straining the fluid.

Another object of the invention is to provide means whereby the cream to be strained will be spreadso that'it will be evenly distributed upon the straining material.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in ,the accompanying drawings, in which Figure 1 is an end view of the device, showing its association with the pastuerizing tanks. 7

Figure 2 is an enlarged end. view of the strainer supporting frame. v

Figure 3 is a sectional 'ew on line-33 of Figure 2. 7

Referring to the drawings 1 designates a support which consists of cornerposts 2, each post having fixed to its upper end a bracket 3, and said brackets being disposed in pairs upon the ends, of the supports. J ournaled in the brackets are the trunnions 3 of the rollers 4 and wound upon said roll ers is a sheet of cheese cloth, or other suitelement of the device.

of the strainerwilil be presented during the strainin'gfoperation.

*f Suit ably' i sigfpported above the 1 I e tubef8, tlie a vertically d sposed discharg upper end of which isconnected with a union 9, said union,havingsupportedrthera by a rod 10 ,s i' 1r d be ng; posed iax' flf y WitlfinJ the tube "8 and is secured *to the shank 11 of the conical spreader 12. Lead- .ing tothe union 9 is a pipe 13 in order that the cream will be conducted. to the tube 8 and will be spread by the spreader 12 and it leaves saidtube to gravitate to the strainer. In this manner a proper I tribution and spreading of the cream is assured.

vat

dls' 5 I Supported by the posts 2 and immedi- V ately' under the strainer 5 is a hopper 14' it being obvious that the strained fluid will I gravltatelnto thehopper and flow therefrom through the pipe assembly 15 to one of thespasteurizing tanks 16, said tank being connected with the other tank 17 bya pipe assembly 18, as is customary. Owing to the presence of the chain 7 the rollers can be rotated in order that the straining material can be rolledfrom one to the other in order that a clean portion of the material can be brought under the spreader 12 when desired, and without stopping the straining operation.

' It will be of course understood that if desired one of the rollers may be driven by a motor in order that the straining cloth can be wound very slowly from one roller construction, may

be resorted to without 5 to the otherso as to constantly present a l' departing from the spirit or sacrificing any of the advantages of the invention.

We have illustrated the strainer used in connection with the pasteurizing tanks, but it Will be of course understood that a strainer constructed in accordance with our in vention can be used with equal success for straining fluids other than cream.

What is claimed is A device of the class described comprising a support, a pair of rollers revolubly mounted upon the support, sprocket wheels connected with the rollers, an endless sprocket chain trained around the sprocket wheels for simultaneously rotating the rollers, a sheet of screening material windable upon actuation of the chain from one roller to the other in a plane below the longitudinal axes of the rollers, and means for discharging liquid upon the sheet, one stretch of the chain serving to prevent rotation of the rollers when the sheet is subjected to the weight of fluid, whereby abnormal sagging of the sheet is prevented.

In testimony whereof we aflix our signatures. I JOHN A. BATHEN. [n s] WILLIAM F. IN GRAHAM, JR. [1 s.]
